Abstract

PURPOSE:To restrain the operations of a piston and a mechanism body engaged therewith by a method wherein the piston itself serves also as an unloading valve body and the piston starts to pass through an unloading hole when each stroke is finished. CONSTITUTION:The unloading hole 6 for restricting the operation stroke of the cylinder and a return hole 7 allowing a working oil on the back side of the piston 2 to pass there through are provided on the circumferential surface of the cylinder 1. The larger one of inside-surface distances between the holes 6, 7 is set to be approximately equal to the thickness B of the piston 2, and a restricting hole 8 for restraining the movement of the piston 2 is provided on the front side of the return hole 7. When the oil is continuedly fed into the cylinder 1 via an inlet 3 by operating a pump 10, the piston 2 is pushed to close the unloading hole 6. When the cylinder 1 is extended further, the piston 2 also closes the return hole 7 so that the oil on the back side of the piston 2 flows out only through the restricting hole 8 to increase the internal pressure.
